Title: Automatic vehicle control system
IPC: B63B45/08
Filed: 1939-12-18
Abstract: 539,741. Photo-electric control of ships aircraft and road vehicles ; controlling by sounds ; preventing collision at sea. WILLIAMS, A. R. Dec. 18, 1939, No. 32451. [Class 40 (iii)] [Also in Groups XXXIII and XXXVIII] Road or rail vehicles, ships or aircraft are controlled by polarized or coloured light or by ultra-audible sound radiated from another vehicle &c. or from a fixed source so that collisions are avoided, means being provided for varying the intensity of the light &c. waves transmitted and of the sensitiveness of the receiver with the speeds of the respective vehicles and if desired additionally with the accelerations. In the case of road vehicles, the control may act on the clutch and/or accelerator, as well as on the brakes, and the controlling energy may be radiated from the front, back and side of cars and from points in the roadway such that passing on bends and collisions at intersections are prevented. Control of road-vehicles. The sensitiveness of the receiver is increased with speed and acceleration and reduced with deceleration and the opposite effect is produced on the intensity of the light transmitted with the aid of two pairs of rheostats controlled respectively by a centrifugal device 63, Fig. 4, and an inertia member 65. The receiving system comprises nicol prisms arranged to pass light polarized in the vertical and horizontal planes respectively and acting differentially on the controlling arrangement. Normal light acts equally on both systems and produces no effect. Received prolonged light however causes in accordance with its intensity the opening more or less of a valve between the induction manifold 27, Fig. 3, and a cylinder 29 of which the piston 28 acts on the brake system. Control of aircraft. In other arrangements, Figs. 10 and 11 (not shown), solenoids acted on oppositely by a receiving system similar to that described for road vehicles are arranged to act on the elevator control or the rudder and aileron controls. The sensitiveness of the receiver varies with the air speed of the craft. Preventing collisions at sea. Ships may be provided with transmitters and with receivers which act on the rudder and engines so as to prevent too close an approach. The receivers may also be acted on suitably by shore transmitters to enable shoals to be avoided. In an arrangement for guiding a ship through a narrow channel, port and starboard receivers are acted on by transmitters on each side.

Title: Binary signal data stores
IPC: G11C11/4094
Filed: 1975-08-05
Abstract: 1522183 Semiconductor data store SIEMENS AG 5 Aug 1975 [11 Sept 1974] 32631/75 Heading H3T A binary data store having MOS storage elements has a read-out amplifier LV2 in the form of a pulsed flip-flop consisting of two inverters each having a switching transistor T6, T7 and a load transistor T8, T9 and with the feedback paths each containing a buffer transistor T 12, T 13 and has the bit-lines DL1, DL2 of the storage elements connected to the control inputs of the associated read-out amplifier, the bit-line selection being effected by a bit-switch BS controlled by a write-in pulse train ST and a bit decoder BD and thus transfers the write-in information to one selected bit line in any cycle. The buffer transistors T12, T13 can either be held non-conductive during write-in until the selected bit line is charged via the bit switch BS and until the switching transistor T6 operated by the selected bit-line DL1 has been set, or they can be held conductive with their ratio W/L lower than that of the switching transistors, W being the channel width and L its length in a given transistor, thus making the internal resistance in the on-state of the cut-off transistors high compared to that of the switching transistors. The ratio W/L of the cutoff transistors may be greater than that of the load transistors. It is stated that either method of operation of the cut-off transistors makes the bitline series resistance R immaterial. In operation a bit decoder BD enables bit switch (T16, Fig. 5, not shown) to pass pulses ST from generator G and these enable a series switch (T15) to pass a '1' or '0' from a write-in amplifier SV to the bit line DL1. Simultaneously, or earlier, a '1' is applied to S3 to put the load transistors T8 T9 into a high impedance state and S4 is held at '0'. Depending on the mode of operation S5 is taken to '0' to turn T12, T13 off or left at '1' leaving them conductive. At the leading edge of the write-in pulse ST the bit line DLI starts to rise, or fall, towards the '1' or '0' applied by the write-in amplifier. The second bit line DL2 follows in the inverse sense after a delay if T12, T13 are off, or if they are on the transition 1 to 0 starts immediately and that of 0 to 1 after a shorter delay.

Abstract: 1,024,834. Measuring electrically. S. SMITH & SONS (ENGLAND) Ltd. June 14, 1963 [March 15, 1962], No. 33174/61. Heading G1N. [Also in Division G3]. Apparatus for comparing the outputs from three similar transducers operating simultaneously comprises three magnetic amplifiers, each with two control windings fed with a different two of the measuring signals, selectively operating alarms when the difference between two signals exceeds a predetermined amount. As shown (Fig. 1) three similar vertical gyroscopes VGA, VGB, VGC, on an aircraft, produce signals P A  &c. proportional to the pitch and signals B A  &c. proportional to the bank of the craft. The signal P A  from gyro VGA is converted to a DC potential at 14 (Fig. 3) and fed to a control winding 17 of a magnetic amplifier 18, in opposition to the signal P B  from VGB fed to a second control winding 20. If these signals differ by more than a predetermined amount a DC output is obtained from amplifier 18 which is fed to a further magnetic amplifier 23, causing the de-energization of relays 1AB, 2AB. In a similar manner the bank signals B A , B B  are compared in a magnetic amplifier 21, and cause de-energization of relays 1AB, 2AB when the difference between the bank signal exceeds a predetermined amount. The contacts of relays 1AB, 2AB &c. selectively control a series of indicators W A  &c. (Fig. 2) so that when e.g. gyro VGA is faulty this is indicated at W A . A further indicator C W  is operated when all three gyros give different signals. The apparatus may be associated with an automatic flight control system, intoducing change over to manual control when a faulty gyro is sensed.

Abstract: 734,256. Making tubes and containers. FERRAND, G. A. Nov. 30, 1953, No. 33255/53. Classes 83 (2) and 83 (4). Altering physical structure; jointing by stamping.-A process for the manufacture of hollow steel bodies by super-pressurizing in a mould is characterized in that the mould is formed by movable separate and distinct members which are taken away after the expansion of the wall, said members being spaced along the length of the hollow body. Two part rings 11, assembled by bolts 12, are placed around a tube or container 10 to be super-pressurized. The tube and rings are mounted between the plates 13 and 14 of a hydraulic press and pressure fluid is admitted into the tube to expand it until it rests against the rings 11 the initial clearance between the rings and the tube determining the degree of expansion. Circular spacers 15' may be placed within the rings 11 and the internal pressure is applied progressively so that the tube is first expanded to contact the spacers 15. The pressure is then released and the spacers removed after which the pressure is re-applied until the tube is expanded to contact the rings 11. Finally, the pressure is released and the rings removed. Alternatively; the rings may be left on the tube, the pressure being continued until the rings are under elastic tension. The shortening of the tube during the expanding operation is compensated for by adjusting the plate 13 or 14 of the press or by providing a sliding joint between one of the plates and the tube or container. This joint may also produce a longitudinal compression of the tube to prevent reduction of the tube wall. Specification 671,609 is referred to.
